Clojurians Log v2

If you mean as an argument to a Clojure function, wrap it in a function like #(UUID/randomUUID)

As an argument to a java static method 🙂

I would hesitantly suggest using a lambda expression, but I've not used them in Java 😄

That seems right

In Java or in Clojure?

In Java, as a Class::method method reference

From Clojure right now, you’ll need to reify a Java functional interface (but this is an area of active work)

This is a pure java question What's the type of that argument? How do I invoke the method I passed as an argument?

it depends on the method

it's being treated as some kind of functional interface, so a method that is Object f(Object) could be typed as a java.util.function.Function for example

clojure.lang.Util/equiv and clojure.lang.Util/equals 🙂

BiPredicate?

what are you passing it to?

BiPredicate is probably the best match there

I have a couple of static methods whose only difference is which static method they're calling, equiv/equals

You can make your own interface

interface EqualityMethod {
    static EqualityMethod EQUIV = clojure.lang.Util::equiv;
    static EqualityMethod EQUALS = clojure.lang.Util::equals;
    boolean areEquivalent(Object a, Object b);
}
